Not really production because the traffic is low, but I run http://ichi.moe http://ichi.moe on SBCL (Hunchentoot web server) and I never had to restart it because of memory leak or a crash. I usually hot-swap the updates and the same server process stays up for months. It also heavily uses JSON and XML and the libraries for them (jsown and cxml) are perfectly adequate.
